随着天然林的减少和营林科技的进步,速生丰产林建设成为世界林业发展的重要趋势,并且在许多国家取得重大成就。速生丰产林建设的成就与这些国家的经济扶持和采取的一系列措施是分不开的。定向培育、林工结合、依靠科技进步是各国的普遍经验。速生丰产林发展也带来一些问题.如林木病虫害、地力衰竭、生态环境破坏,以及速生材利用等,这些问题严重地制约速生丰产林的发展。
With the reduction of natural forests and the progress of science and technology in silviculture, the construction of fast-growing and high-yield forests has become an important trend in the development of forestry in the world and has made great achievements in many countries. The achievements of fast-growing and high-yield forest construction are inseparable from the economic support and the measures taken by these countries. Oriented cultivation, forestry and industrial integration, relying on scientific and technological progress is the universal experience of all countries. The development of fast-growing and high-yield forests also brought some problems, such as forest diseases and insect pests, soil failure, ecological environment damage, and the use of fast-growing timber, which severely restrict the development of fast-growing and high-yield forests.
